Asthma, rhinitis and eczema symptoms in Quito, Ecuador: a comparative cross-sectional study 16 years after ISAAC.

18 For example, repeated studies in the Netherlands showed a decreasing trend in asthma symptoms from 13.4% in 1989 to 6.2% in 2010; however, this trend was contrary to rhinitis symptoms. 19 Similarly, a study conducted in southern Taiwan showed a decline in the prevalence of asthma symptoms as doctor diagnosis, exercise-induced wheeze and nocturnal cough. 20 However, contrary to our results, many studies suggest a continued increase in asthma prevalence, especially in LMICs. 21 In Ecuador, several studies conducted in different cities have estimated the prevalence of asthma and other RAD.
